So, we hypothesized that the DK-mini-culotte stenting is not only feasible technically but also may be superior to or at least not inferior to the DK-crush stenting in terms of reducing in-stent restenosis and MACE. Hereby, we now carry out a head-to-head, prospective, multicentre, non-inferior, randomized and controlled study to compare DK-culotte stenting versus DK-crush stenting in the treatment of TBL.
